RUBBER HEEL.

Application led September 28, 1921.. Serial No. 503,909.

To all whom. t may concern Be it known that I, IVALTER ENoCH, a citizen of thev United States, residing at IVorcester, in the county of IVorcester and State of Massachusetts, have invented certain new and useful Improvements in Rubber Heels, of which the following is a specification.

My invention relates to improvements in rubber heels, and its principal object is to provide a construction of rubber heel tending to counteract the tendency of many people to wear the heels crooked.

I accomplish this object by so constructing the heel that it is capable of greater compressibility, or yielding to a greater extent, at the part where the wearer has a tendency to work the heel crooked than at other parts of the heel.

According to my invention, and in pursuance of the object stated, I provide the heel at the desired place either with a hol-' low'cd out portion by which greater give is obtained or I may fill the hollowed out portion with highly compressible, soft rubber securing substantially the same result.

The invention is illustratively exemplified in the accompanying drawing, in which F ig. 1 is a perspective view of the inner side of a rubber heel, that is the side to be placed adjacent the heel of the shoe, a segment of the heel being hollowed out;

F ig. 2 is a similar view of a further modified form having the entire rear part of the heed hollowed out.

Referring to the drawing and particularly to Fig. 1 thereof` 10 denotes the heel generally, provided with the nail holes 11. A portion of the heel such as that indicated at 12 is hollowed out, it being assumed that 40 the wearer has a tendency to wear the heel crooked at this portion. In order to give the edge of the heel a smooth finish there is inserted at the hollowed out portion a segment 13 of -very soft highly compressible 45 rubber which will give under the slightest pressure and Will offer practically no resistance tothe normal thrust of the foot during walking. v

In the modified form of Fig. 2, the heel 10 50 has its rear end hollowed out at 13c and a semi-circular rim 13li of soft rubber is used to give a finished appearance to the edge of v the heel.

It will be apparent that in all forms of the invention shown above the underlying principle is to permit freedom of motion or compression at the part of the heel where the wearer is likely to Wear it crooked.

The theory upon which my invention is 00 based is that aheel is worn crooked because of greater friction at that part of lthe heel than at the other parts of the heel and I remedy this` condition by reducing friction to a minimum at the affected part of the heel.

A rubber heel having a segmental cut out portion at the rear thereof, said portion being of substantially less depth than the height of the heel, and an arcuatelyshaped 70 marginal strip of rubber having greater re-y siliency than the heel itself and disposed pcripherally about the cut out portion of the heel, the faces of the strip being flush with the corresponding faces/'fof the heel. 75

In testimony whereof I have aiixed my signature.

WALTER ENOCH.
